I am doing a science fair project and I am trying
to see how will different types of soda affect how
far a soda car will go. Can you help me find out
what carbon dioxide does to soda? Your friend,

Answer 1:

I like that experiment. Carbon dioxide is a gas
that is pushed into soda, so it starts coming back
out of the soda as soon as you open it. I'm
guessing there's a difference in how far the soda
car goes if you shake the soda before you open it,
or if you don't shake the soda. Any soda with
sugar in it will be sticky, so I hope you have a
place to test your cars where that's ok.

The fizz that bubbles up when you crack open a
can of soda is carbon dioxide gas
(CO2). Soft drink manufacturers add
this tingling froth by forcing carbon dioxide and
water into your soda at high pressures—up to 1,200
pounds per square inch.

Carbon dioxide is the gas that makes soda fizz. I
don't know what a soda car is, but if it's a car
that uses the bubbling of soda to propel itself,
then the more carbon dioxide in the soda, the
more propulsion the car will have.
